SPECIFICATIONS15 inch forks on columns 1 and 2 & 22 inch forks on columns 3 and 4

(68,000lb Capacity)

1. GENERAL DESCRIPTION

1.1 The purpose of these specifications is to define a mobile wheel contact lifting system to elevate large buses, trucks, passenger cars, and other vehicles for the purpose of inspection, maintenance, servicing, and cleaning.

1.2 A lifting system shall consist of at least one main lifting column and one secondary column. It shall be possible to form a variety of lifting system configurations using any combination of main and secondary column pairs. All column pairs shall be numerically consecutive. For example, columns 1 and 2 are a pair and columns 3 and 4 are a pair. A set of four may consist of columns 1, 2, 3 & 4. The control system shall allow the flexibility of breaking up sets to be used as sets of two in geographically separate areas or combining sets to create a set of up to eight without modifying the electrical system.

1.3 The lift system shall be approved and certified by the ALI (Automotive Lift Institute) certification program for automotive lifts and shall meet the requirements inherent in the testing of the program, including mechanical as well as electrical testing to ANSI/ALI ALCTV-2006 Standard for Construction of Automotive Lifts and UL-201 Standard for Garage Equipment. The ANSI/ALI ALCTV-2006 standard is the one and only nationally recognized standard for vehicle lifts. Proof of certification as well as testing report showing testing at the certified capacity of the lift must be submitted with bid at the time of bid. ETL is an ALI sponsored independent nationally recognized testing laboratory (NRTL) approved by OSHA. (ETL, an independent NRTL, administers the ALI certification program.)

1.3.1 The lift system shall be fabricated by a manufacturer of the U.S. with a minimum of 10 years of experience fabricating this type of equipment.

1.4 The lift system shall be designed to permit combining multiple sets without modifications to the electrical or mechanical configuration of the lifting columns. The lift system shall be designed as to be able to handle up to 8 columns in a lifting system (or 144,000 lbs.), with the possibility of operating one column, one pair or all of the columns together.

1.5 Control cables shall be disconnected from control boxes at both ends of the cable. Mobile lift systems with control cables “hardwired” into the control box shall not be acceptable due to the difficulty in replacement and loss of operating flexibility.

Mohawk MP-18 24 VDC Series Mobile Column Lift Specifications of 16

Mohawk MP-18 24VDC Series lifts with 15” & 22” Forks.

1.5.1 Control/communication cables shall be no more than 3/8 inch diameter cable and no less than 10 meters (32.8 feet) long, to easily wrap around lift cable holder hooks.

1.6 Control cables shall attach to the columns in an open-ended daisy chain fashion. The opening of the cable loop shall provide access to vehicle entry into the lifting zone without having to drive over cables. Systems that incorporate a closed-loop cable system that cause the operators to drive over control cables are not acceptable.

1.7 Columns shall be structurally designed as to have motor and hydraulic pump assemblies positioned at the bottom of the column to promote greater stability while moving the column. Lift systems with motors mounted on the top of the column shall not be accepted due to their inherent top-heaviness and possibility of tipping while moving.

1.8 Each column shall be equipped with a 3 KW (4 HP) 24Volt DC motor. Motor bearings shall be sealed for life and pre-lubricated for a minimum of 5 years use.

1.9 The floor pressure requirements for each column shall not be greater than 775 psi to ensure stability. Lifts which, when loaded, have concentrated weight on the wheels or the wheel axles are not acceptable.

1.10 The lift shall be suitable for use on any level service that meets the loading requirements stated above.

1.11 The lift maintenance shall be limited to monthly and yearly visual checks to insure that the hydraulic fluid levels are correct and that lift safety systems are functioning properly.

2. LIFTING CAPACITY

2.1 15 inch long lifting forks: Each lifting column shall have a nominal rated capacity of 18,000 lbs. per column; 36,000 lbs. per pair, 72,000 lbs. per set of four; 108,000 lbs. per set of six columns; or 144,000 lbs. per set of eight columns. One pair of columns, rated at 36,000 lbs, must be capable of lifting the heavy rear ends of customer’s heaviest vehicle axle. Vehicles weighing more than 36,000 lb on the rear axle require an additional pair of columns, or heavier rated columns.

2.2 22 inch long lifting forks for lifting both rear tires: Each lifting column shall have a nominal rated capacity of 16,000 lbs. per column; 32,000 lbs. per pair, 64,000 lbs. per set of four; 96,000 lbs. per set of six columns; or 128,000 lbs. per set of eight columns. One pair of columns, rated at 32,000 lbs, must be capable of lifting the heavy rear ends of customer’s heaviest vehicle axle. Vehicles weighing more than 32,000 lb on the rear axle require an additional pair of columns, or heavier rated columns.


2.3 Combinations of 15 inch and 22 inch long lifting fork columns shall be specified, a four column lift consists of two front columns with 15 inch long lifting forks (rated 18,000 lbs each) and two rear columns with 22 inch long lifting forks (rated 16,000 lbs each) for a system that is rated 68,000 lbs total. Various other combinations are available.

3. LIFTING HEIGHT

3.1 The lifting height of each fork shall be no less than 67 inches as measured from the ground to the bottom of the lifting fork (stroke).

4. LIFTING SPEED

4.1 The lifting speed shall not be less than 45 inches per minute either in the ascent or descent mode.

5. CONSTRUCTION

5.1 Lifting Columns:

5.1.1 Upright frame shall be constructed of 3/4 inch thick, high strength R34 fork lift mast channels to ensure structural integrity and provide a smooth lift guidance system. Channels shall be braced with 1/2 inch thick steel plates at a minimum of 3 times along the length of the post to resist channel spreading/bowing when loaded. Formed steel and I-beam construction columns shall not be acceptable as they do not afford the required strength and rigidity.

5.1.2 The base shall be of a U-shaped design with square rear corners, which contact the garage floor when raising a vehicle, so as to provide maximum rigidity, stability and balance during lifting operation. Lifts which, when loaded, have weight loaded on the wheels are not acceptable. Lifts which, when loaded, have weight loaded on small 12” x 12” area column bases only are not acceptable.

5.1.3 Columns shall have multiple covers to allow access to the mechanical lock mechanism, the sensing cable connection to the bottom of the carriage, and rear access to the hydraulic lines at the cylinder base.

5.1.4 The two front wheels shall be spring loaded and shall retract when the lift column is loaded. This retraction shall cause the columns to bear on the floor thru steel plates, resulting in evenly dispersed low compression forces on the floor, not line loads at wheels. Non-retractable wheels that support the lifted load are not acceptable.

5.1.4.1 Contact area of each column’s base plates on the concrete floor shall be a minimum of 350 square inches, and shall not exceed 775 psi (lbs per square inch) when fully loaded.


5.1.5 To Promote Horizontal and Lateral Stability Individual Column Dimensions Should Measure:

5.1.5.1 Base width-45 ½ inches for 15 inch fork models (Columns 1 and 2)51 ½ inches for 22 inch fork models (Columns 3 and 4)(to

accommodate up to 53” diameter tires)

5.1.5.2 Base length-50 inches for 15 inch fork models (outside of pallet jack to end of column “feet”) and 57 inches for 22 inch fork models.

5.1.5.3 Column Height with carriage in low position - 96 ½ inches max5.1.5.4 Column Height with carriage in high position - 142 ¼ inches max

5.2 Lifting Carriage:

5.2.1 Lifting carriage shall ride on maintenance free, double sealed, self lubricating steel barrel-type bearing rollers. Nylon rollers or sliding blocks shall not be accepted because they have a higher coefficients of friction resulting in a higher working pressures for the hydraulic system, and thus, shorter life expectancy on the power units and because they require regular greasing. Ball-type bearings shall not be accepted because their axial load ratings are not as high as barrel-type bearings.

5.2.2 Side load slide blocks shall be provided on the carriages to resist offset loading of the columns. These slide blocks must be accessible and replaceable from outside of the column without having to remove the carriage. Any carriage design that requires removal of the carriage to replace the lifting slide blocks is not acceptable.

5.3 Lifting Forks

5.3.1 The distance between the wheel contact forks shall be hand adjustable from 10 inches to 22 ½ inches. Wheel contact forks shall freely accept tire sizes between R10 and R22.5 inclusively, thereby accommodating vehicles with up to 48 inch diameter tires and 24 inch rims. Wheel reducer sleeves (sleeve adaptors) shall not be acceptable as they may slip off of the lifting forks causing a vehicle to fall.

5.3.2 Standard fork length shall be no less than 15 inches, to accommodate balloon and flotation tires.

5.3.3 22 inch long lifting forks are designed to support dual inside and outside tires on dual wheeled axles or to accommodate super single tires. 22 inch fork length reduces per column capacity from 18,000 lbs. to 16,000 lbs.


5.3.3.1 All 22” forks shall have handles welded on tips of forks for ease of movement.

5.3.4 Forks shall be wedge shaped with an angle not to exceed 30 degrees. This enables the forks to be adjusted closer and support the hub in the case of a flat tire. Forks with angles exceeding 30 degrees are not acceptable, due to difficulty of positioning the columns.

5.3.5 All forks shall be provided with fork locking pins (hitch pins) of no less than 3/4 inch diameter. Staggered fork pin locking holes, easily accessible on top of carriage tube and fork tubes, shall provide variable adjustment settings for fork widths. Forks that use small clips, steel tabs, friction bolts, or hard-to-access retaining pins to maintain width settings are not acceptable. Non-adjustable forks that use wheel reducer sleeves are not acceptable.

5.4 Lifting Clearances

5.4.1 The clearance between the lifting column and the back of fork shall be no less than 9 1/2 inches, for operating a single column when lowering onto a jack stand.

5.4.2 The clearance between the carriage extension and the back of the fork shall be 10 ¼ inches minimum.

5.4.3 Carriage shall have 1/8 inch minimum clearance from the floor when in the low position, to facilitate moving the column when power is cut-off.

6. PALLET JACK MECHANISM

6.1 The lifting columns shall be easily moved by one small person using a pallet jack system with two spring loaded front wheels consisting of at least 6 inch diameter aluminum core with polyurethane tread and straight bearings and dual 6 5/8 diameter thermo set resin coated steering wheels at the rear of the jack. The rise of the pallet jack shall be 1 ½ inches minimum. Smaller wheels, single rear wheels, solid steel wheels or plastic wheels that do not allow easy column movement will not be considered due to difficulty moving columns over floor expansion seams, cracks, small rocks, washers or shop debris on the garage floor.

6.2 The pallet jack will have the ability to turn 90 degrees and allow sharp turning of the column in tight areas.

6.3 The pallet jack mechanism shall have an OSHA approved loop type handle and shall be raised and lowered using a three position lever with raise, lower, and neutral position. T-bar handles are not acceptable since they do not facilitate proper handling of the mobile column.


6.4 Pallet jack mechanism shall have an overload valve that will automatically lower the jack if the operator attempts to raise a vehicle with the pallet jack in the raised position. The overload valve shall be set and sealed at the factory and adjustable in the field if necessary.

6.5 The pallet jack mechanism shall be rated for a minimum of 5,000 lbs. Yet the pressure relief setting will cause the column to lower to the floor if 500 lbs. of pressure is applied to the lift’s columns.

6.6 The two front wheels shall be spring loaded and shall retract when the lift column is loaded. This retraction shall cause the columns to bear on the floor thru steel plates, resulting in evenly dispersed low compression forces on the floor, not line loads at wheels. Non-retractable wheels that support the lifted load are not acceptable.

6.6.1 Adjustment of the spring loaded front wheels is accomplished thru ¾ hex socket adjustment screws located on top of each wheel assembly.

6.7 The pallet jack and front wheels shall all retract during normal lifting of vehicles to ensure pressure is applied to floor thru the large stable lift base area. All lifts that do not jack, and are always supported by wheels, are not acceptable as they roll prior to being raised.

7. CONTROLS

7.1 The various functions of the mobile lifting system shall be controlled from the control panels on the columns.

7.1.1 All columns and all functions shall be clearly labeled in easy to understand English and not symbolic functions.

7.3 It shall be possible to form a set of lifts using any combination of consecutively numbered column pairs. All column pairs shall be numerically consecutive. For example, columns 1 and 2 are a pair and columns 3 and 4 are a pair. A set of four may consist of columns 1, 2, 3, and 4. The control system shall allow the flexibility of breaking up sets to be used as sets of two in geographically separate areas or combining sets to create a set of up to eight without modifying the electrical system.

7.4 Individual operation of each column shall be achieved by simultaneously turning and holding the spring loaded operation mode selector switch to the SINGLE position and pressing the UP or DOWN button on that column. Lifts that use operation mode selector switches that are not spring loaded shall not be accepted due to the possibility of inadvertent switching by other operators in the shop.

7.5 Paired column operation shall be achieved by simultaneously turning and holding the spring loaded operation mode selector switch on either of the two columns on the axle to the PAIR position and pressing the UP or DOWN button on the column. Lifts that require a complicated sequence of pressing reference buttons on multiple columns shall not be accepted.

7.6 Paired or individual operation shall be permitted at any time during the lifting cycle. It shall be possible to switch from SINGLE, PAIR, or ALL operation in any order regardless of the height position of the lifting carriage.

7.7 The control system shall utilize an off the shelf Horner brand PLC (programmable logic controller) to ensure proper operation of the lift. The PLC shall have a LCD display to display lift status and facilitate trouble


shooting. Printed and dedicated circuit boards, impossible to obtain from any company except the OEM manufacturer will not be accepted.

7.7.1 The PLC shall have function keys that allow the user to display post ID, post height, post voltage, user settings, and maintenance information.

7.7.2 The PLC screen shall display lift operations and the status of any errors the lift witnesses, facilitating troubleshooting.

7.8 All wiring within electrical enclosures shall be numbered to assist in trouble shooting. Units with un-numbered wires are not acceptable.

7.9 One communication control cable shall be supplied per column. These cables shall have female plugs on both ends. Mobile lift systems with control cables “hardwired” into the control box shall not be acceptable due to the difficulty in replacement and loss of operating flexibility.

7.10 Level and height sensing of each column shall be achieve by use of a NEMA 4 potentiometer or linear transducer. Potentiometer shall be of an absolute sensing type, which will provide reliable height sensing feedback to the controls and retain values in event of power shutoff. Height sensing by use of a proximity sensor or other means that use a chain or timing belt linkage system shall not be acceptable due to the susceptibility of failure and mis-adjustment of these systems.

7.10.1 Sensing line shall be attached to carriage with 45 lb rated stainless steel leader line and shall attach with a simple lock swivel.

7.11 Male connection ports for communication cable entry shall be equipped with twist-on caps to prevent dirt, dust and water entry.

7.12 Communication between columns must take place via communication cables. Due to static electricity and/or vehicle emergency band radio signals, columns that communicate via a ”wireless” system are not acceptable.

8. BATTERY POWER

8.1 Each post will be equipped with (2) two 12 Volt DC, Size D, deep-cycle, heavy-duty marine-type, sealed, maintenance-free valve-regulated lead-acid, gel-type and absorbed glass mat batteries.

8.2.4 One female 120 VAC outlet, which can accommodate any standard 120 VAC extension cord (with ground), shall be provided on each control box to provide power to the charger. Each charger draws 5 Amps.

9. DRIVE MECHANISM

9.1 The drive mechanism shall be hydraulic drive and shall permit lifting and lowering without any pulsation, jerks, or unsteady lifting. Lifting and lowering shall be smooth.

9.2 Hydraulic system shall comprise an electrically-powered pump, internal flow control valves, one full speed down valve, one half-speed down valve, and a fluid reservoir. Working pressure at full load shall not exceed 3000 psi.

9.3 Hydraulic power unit shall be from a U.S.A. manufacturer.

9.4 Hydraulic lifting cylinder shall be piston type. Cylinder casing shall be mounted on the column base and the barrel shall be enclosed in the carriage to protect it from debris and damage. Chrome hydraulic cylinder rod shall be 2 inch diameter minimum. Piston diameter shall be 3 inch diameter minimum. Barrel outside diameter shall be 3 ½ inch diameter minimum.

9.5 If necessary, the removal and re-installation of the lifting cylinder shall take place in less than 30 minutes per column. Due to the extensive amount of time and costs involved in repairing screw drives, screw drive systems are not acceptable.

9.6 Stainless steel hydraulic tubing with a minimum burst rating of 5:1 shall be used to contain pressurized hydraulic fluid. Rubber hydraulic hoses are not acceptable.

9.7 The hydraulic unit shall be equipped with dual lowering and lifting valve systems for smooth operation and equalization. Lifts with column pairs that come to a complete start or stop in normal operation (due to unevenly loaded vehicles) are not acceptable.

9.8 Each hydraulic cylinder shall be equipped with a velocity fuse to prevent decent in the event of a major leak. Velocity fuses shall be a fitting type that is easily replaceable. Velocity fuses must be fabricated by a North American manufacturer that specializes and has several years in experience in fabricating these hydraulic safety valves.


9.9 Cylinder rods shall be chrome plated for low abrasion conditions, seal life, and to prevent slip-stick problems.

10. SAFETY DEVICES

10.1 Each column shall have an automatic multi-position mechanical locking system. This system shall incorporate a spring loaded latch that will automatically engage whether the lift is in operation or not. The column shall have a minimum of 19 lock positions beginning at the lifting height of 12 inches and spaced every 3 inches for the entire stroke of 67 inches. This safety device shall be totally independent from the lifting drive system. Systems that utilize non-load bearing “safety nuts” shall not be approved since they are integrated with the lifting drive itself.

10.2 The mechanical locking system shall be braced to the post by 1/2 inch thick steel plates so that the load is distributed throughout the whole section of the post. Any system that uses a flat plate that loads into a sheet metal column back is not acceptable.

10.3 The mechanical lock shall be released by an electric pull solenoid when the lift is lowering. Pull solenoid shall incorporate a spring when releasing lock to allow electric solenoid locks to “seat” when energized whether lock is free or not.

10.4 A proximity sensor shall be located at each mechanical lock to ensure proper release upon descent. If any lock is not properly released, PLC screens shall indicate which locks are not released, and prevent downward descent of all lift columns until event is corrected.

10.5 Each lock shall have a manual pull type override lever to allow the lock to be manually released so that a vehicle may be lowered in the event of a loss of battery power or a system failure. This lever shall be easily accessible without disassembling any lift components. In this unlikely event, lifts that take a single person more than 15 minutes to lower, or require special tools or cranks are not acceptable.

10.6 The lift shall incorporate a PARK button that allows the loaded carriages to be fully lowered on the mechanical locks, removing pressure from the hydraulic systems. Any design that has mechanical locks, which does not allow the load to be lowered onto the locks is not acceptable.

10.6.1 Verification of hydraulic pressure being removed from the system can be visually seen by use of optional weight gauges. When load is lowered onto mechanical locks, the weight gauges read zero.

10.6.2 Verification of a level floor that falls within the safe lifting guidelines for this type of equipment (3 degree slope or less) can be visually seen by use of optional floor slope indicators.


10.7 The lifting system shall incorporate multiple redundant safety systems. The lift shall support the vehicle in the event of a mechanical failure, motor failure, hydraulic failure or loss of electrical service by consisting of electrical, mechanical and hydraulic safety systems.

10.8 Motive UP and DOWN push buttons shall be of a type requiring pressure be maintained on the buttons by the operator in order to operate the lifts.

10.9 Cable hooks shall be provided on both sides of each column and made of steel construction to provide convenient and safe storage of cable when the lift is not in operation.

10.10 LCD screens on each control box shall illuminate, indicating when each column is switched ON. The screen shall also indicate which columns are connected and powered and require the user to approve of the system configuration prior to lifting.

10.11 A safety logic circuit will be incorporated into the electrical system to ensure that the lift shall not operate unless all the control cables are located properly, all the emergency stop buttons are released, and all columns designated for the system have been approved by the user, through user confirmation entry button feature on the LCD screen.

10.12 A motion control system shall monitor the up and down motion of the lifting carriages and correct any difference of +/- ½ inch in the travel height of the carriages. If the difference in speed cannot be corrected, the system shall fault and stop all the columns when the difference between any lifting carriages becomes greater than 2 inches.

10.13 In the event of a fault, the PLC screen shall indicate what specific fault is present and at which column it has occurred. Lift faults shall be clear and easy to understand, displayed on all posts, and listed in the user manual.

10.14 Each control panel on each column shall have a mushroom type emergency stop switch which stops the movement of all of the columns. The emergency stop switch must be palm operated and shall require clockwise motion in order to be released.

10.15 All control voltage shall be no greater than 24 volts DC.

10.16 In the event of a low battery condition or pump failure, emergency manual lowering of posts shall be made possible by the use of manual lowering valves at each pump and manual lock release levers. Lift shall be able to be lowered without the use of tools and accomplished by one technician in less than 15 minutes.

Said bumper adaptor will leave the vehicle wheels and tires free hanging and permit full under-vehicle access. To accommodate different vehicle frame widths, contact with vehicle will be accomplished via a range of horizontal mounted stackable 3” adaptors and 3”x3” frame contact lifting pads. This option shall be approved and certified by the ALI (Automotive Lift Institute) certification program for automotive lifts and shall meet the requirements inherent in the testing of the program, including mechanical testing to ANSI ALI/ALCTV-1998 Standard for Construction of Automotive Lifts.

12.7 Winged Snow Plow Adaptor (or RV Slide Adaptor), to allow lifting of vehicles where the normal operation of the column cannot contact the tire without removing a snow plow. A wing plow adaptor option is available. Said adaptors allow immediate lifting of a wing plow truck with no column modifications nor removal of the trucks plow. Wing Snow Plow Adaptors are rated at 24,000 lbs per pair of posts. This option shall be approved and certified by the ALI (Automotive Lift Institute) certification program for automotive lifts and shall meet the requirements inherent in the testing of the program, including mechanical testing to ANSI ALI/ALCTV-1998 Standard for Construction of Automotive Lifts.

12.8 Chassis Lifting Beams. In order to raise a framed vehicle by the vehicle’s frame or jacking points (i.e. school buses) a chassis lifting beam option shall be available. Chassis lifting beams shall contact each pair of lifting columns, supported by lifting forks, and allow a vehicle to be lifted from horizontally sliding contact pads to accommodate a variety of vehicles. Chassis lifting beam is rated 35,000 lbs. This option shall be approved and certified by the ALI (Automotive Lift Institute) certification program for automotive lifts and shall meet the requirements inherent in the testing of the program, including mechanical testing to ANSI ALI/ALCTV-1998 Standard for Construction of Automotive Lifts.

12.9 Optional Automotive Frame Adaptor, will slip over lifting forks to allow any pair of columns to raise normal passenger cars or light pick-up trucks (up to 8,000 lbs.) by the vehicle frame leaving the tires free for tire and brake service, with the columns positioned on the each side of framed vehicles. Side by side, auto frame adaptors will leave vehicle undercarriage open and accessible for all repairs. Auto frame adaptor will slide perpendicular to the column (parallel to vehicle lifting points) and expand or contract for different wheel based vehicles. Any auto frame adaptor that requires lifting forks to be removed (non-slip on) will not be considered due to time required of removing forks and installing auto frame adaptor. Due to the nature of this design being outside the base envelope of the post, this





is a non-certifiable option, and therefore, use of this option on lift voids certification of lift.

12.10 ST-2000 Scissoring Transmission Jack Table (Optional) Maximum capacity of table is 2,000 lbs. This lift table handles power train components like engines and their

transmissions, engines with transaxle assemblies, rear ends and large electric vehicle batteries. It will also serve as a work table where components can be lowered to a convenient work height for repairs.

Dimenions:Height fully lowered: 31 inchesHeight fully raised: 80 1/2 inchesTable Width: 19 inchesTable Length: 36 inchesOverall Dimensions: 31”W x 56”L x 34 1/2H

Table comes equipped with (4) 8 inch diameter swivel casters for easy maneuverability. Front wheels can be locked in position for steering. Rear wheels can be locked to prevent the lift from rolling.

Table comes equipped with an air/hydraulic foot pump with a metered valve for safely lowering load.

Five foot extension hose with quick disconnect fittings stores in the lift base. The foot pump can be removed from its holder and hydraulic hose quickly and easily extended using the extension hose. This provides hands free operation of the pump anywhere around the lift table’s perimeter.

Scissor lift table design provides easy 360 degree access to any component.

Two heavy duty ratchet tie-downs are included to safely secure the load on the lift table.

Twin threaded rods with ¾ inch hex heads can be adjusted with common ratchet or hex driver, to adjust table tilt angle +/- 15 degrees, from front to back, or from side to side.

All lift options must be compatible and ALI certified to ANSI/ALI ALCTV with base model lift. If not, then entire lift is not ALI certified.
